    • A lighting system and device for providing indirect light using free-cavity, double-diffusing configurations are disclosed. In accordance with the embodiments of the invention, a lighting fixture comprises a cover structure with a diffusion layer and a reflective plate that form the free-cavity. The free-cavity is preferably configured to provide an output of light from a light source positioned within the free-cavity with an efficiency rating of 70% or more and provide better than an 8:1 ceiling lighting contrast between the rows of fixtures with rows on 16 feet spacing. Further, in accordance with a preferred embodiment of the invention, a device is configured to couple to a ceiling structure and provide the indirect lighting from a fluorescent light source.
    • 公开了一种使用自由腔,双扩散配置提供间接光的照明系统和装置。 根据本发明的实施例,照明器具包括具有扩散层的盖结构和形成自由腔的反射板。 自由腔优选地被配置为提供来自位于自由空腔内的光源的光的输出,其效率等级为70%或更高,并且提供优于具有行的固定装置行之间的8:1顶棚照明对比度 在16英尺间距。 此外,根据本发明的优选实施例,设备被配置为耦合到天花板结构并且提供来自荧光光源的间接照明。
